Why is the FBI classifying some of Hillary Clinton's emails to prevent release?

During a press briefing on Friday, White House press
secretary Joshua Earnest said that reporters should ask the FBI about
what led the agency to retroactively classify some of Hillary Clinton’s
emails.
The State Department released 296 pages of Clinton’s emails related
to Libya and Benghazi on Friday. The Associated Press reported shortly

not send or receive classified documents on her private email account.
Asked about the classified documents, Earnest twice referred
reporters to the FBI, which made the determination to classify some of
Clinton’s records.

not uncommon for the materials included in the review to be classified
based on current events,” Earnest said.Keep on reading…
